This is the only ioctl command that does not have a proper compat handler. Making the normal implementation do the right thing is actually very simply, so just do that by using an in_compat_syscall() check to avoid the special case in the pkcdvd driver.
Since this uses blkdev_compat_ptr_ioctl() it needs to be moved after the following patch.
Ah right, I obviously reshuffled my patches too much to end up with the most reasonable order and avoid introducing something that would be removed again later.
I'll split out the addition of blkdev_compat_ptr_ioctl() into a separate patch and move that all in front, as I'm no longer sure if there was another dependency in the other way.
